Function of potentiometer
There are many types of potentiometers, and the functions of different potentiometers may vary. However, most potentiometers have three basic functions
1. First function: current control
Some precision potentiometers are capable of current control, only in this way can the current value be accurately obtained. When the selected current output end is the sliding contact lead out end,
the potentiometer can be used to control the current size;
2. Second function: distributing voltage
By utilizing the nearly linear relationship between resistance and voltage, adjusting the resistance value can adjust the voltage distribution relationship and achieve stepless output voltage regulation,
such as in humidifiers and other areas;
3. The third function is to change the resistance
When the input parameter of the circuit is the resistance value, a potentiometer can be used. When the trimmer potentiometer is connected to two end devices,
it can obtain a smooth and continuous change in resistance value within the travel range. At this time, the potentiometer plays a role in changing the resistance.
For example, in humidity control, different humidity levels are displayed by controlling the resistance value.
